DESIGN AND IMPLEMENTATION OF A SIMPLE CALCULATOR TO COMPUTE AREAS AND VOLUMES OF A SHAPE
ABSTRACT
The study traced calculator system as a tool to completely change mathematical knowledge and sophisticated problems solving strategies had advanced the field of simulated engine in mathematic. The aim of the study is to design and implement a Program to Compute Areas and Volumes of a Shape. In achieving this aim, the following specific objectives were laid out as follows to design and develop an application software that will improve the speed of computing the areas and volumes of a shape in such a way that it will reduce complexity in solving with simple calculator, ensure timely processing and change the processing number to ASCLL code, and reduce the problems immensely and provides a release working environment. The motivation that led to this research is that the existing system has low and slow speed of the calculating the areas and volumes of a shape, Inappropriate representation of data, Loss of figure in computation of higher numbers, Inability of handling complex arithmetic operation of areas and volumes of a shape and the processing of numbers are in binary coded decimal (BCD). The methodology adopted in this study is the structured system analysis and design methodology (SSADM) which is a technical approach for analyzing and designing an application or system by applying object throughout the software development process. The programming language used is HTML, CSS, JAVASCRIPT, PHP, SQL and JQUERY. The reason why web programming languages was used is because, it is platform independent and it is a web based application. This project work also focused principally on numbers and arithmetic operation. Interestingly, the end result of simple calculator system was its ability to process number and operators, and provides a useful result. Therefore, this project will help immensely in the following way. Easy calculating of tedious computation of the areas and volumes of a shape, easy to retrieval of errors and it will also be of a good assistance to any researcher on these topics.
CHAPTER ONE
1.1 Introduction
Today’s scientific calculators are highly powerful and if their operation is properly understood, a little innovative imagination can do wonders. Long calculations are a normal part of design and analysis, where students spend time like anything, and conclude the computational procedure in distaste. As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitations of the Study and Definition of technical terms.
1.2 Background of Study
Today’s world is of science and technology. Science has pervaded in other branches of knowledge, it has become difficult to think a subject thoroughly explained without inviting science to help. More insight into the natural phenomena are required and as a way, they demand computations. Subjects specifically related to engineering and technology, are heavily computational. Fortunately, powerful computing devices are readily available and in every body’s reach. It has been observed that usually students buy scientific calculators. But it is a pity that most of these students usually imagine the operations of multiplying and dividing, and computations of functions like sine and cosine is the all a scientific calculator can do.
Ever since, tedious mathematical problems in the organization is not a simple one, that is to say, the process can be said to involve a lot of procedures or protocols which ranges from insertion of figures for tedious calculation, processing of numbers and retrieval of errors. However, because of this, there is the need to accomplish an extensive research to discover the intricacies involved in the entire process. So the researcher decided to embark on this work design and implementation of a simple scientific calculator
Scientific calculator differs a lot from other basic calculators. The basic calculator ignores the order of operations. The main purpose of the scientific calculator has the function that we need to perform the calculation in chemistry, physics, engineering, or trigonometric problems. It has a significant role when the function is being worked with scientific notation. Computer has gone from being fantasies of science, fiction of realities of everyday life, especially in the offices, school (educational organization). This work is a research aimed at solving the above problem. When this system actualizes, it would be received of solving tedious calculations and sophisticated mathematical problems.
